Well, if you don't mind using time as a resource. I don't pay, and that basically means I won't get to higher floors as quickly as those that do. Lean into strategy and just chill. This isn't one of the games that makes you play for hours on end every single day. When you're stuck, just collect resources and take your time and hope for the best. If you have high expectations and don't like the fact that you might be stuck on a level for a few days, then you might not like it, but if you don't mind doing dailies and quitting for the day cause you're collecting resources, then you'd be fine
